Strands of story resume with characters going up to university (6)
I believe the answer is:
fibres
'strands' is the definition.
'story resume with characters going up to university' is the wordplay.
I cannot quite see how this works, but
'story' could be 'fib' (I've seen this before) and 'fib' is present in the answer.
The remaining letters 'res' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'of' is the link.
(Other definitions for fibres that I've seen before include "They may be spun" , "Filaments" , "Long thin substances, threads" , "thin strands or threads" , "Long slender substances" .)
